Peripheral Muscle Strength, Functional Capacity, and Anxiety Levels in Patients Undergoing Coronary Artery Bypass Graft Surgery: Postoperative 4th and 8th Week Comparisons

Abstract

Purpose: This study was planned to evaluate the relationship between peripheral muscle strength and functional capacity anxiety level in the preoperative and postoperative periods in patients who underwent coronary artery bypass graft (CABG) surgery. Methods: Twenty-two volunteer patients who had undergone CABG surgery (mean age 62.4 ± 6.5 years) participated in the study. At the fourth and eighth weeks after CABG surgery, peripheral muscle strength was measured with a digital dynamometer, functional capacity was measured with the 6-Minute Walk Test (6-MWT), and anxiety level was measured with the State and Trait Anxiety Inventory (STAI). The relationships between peripheral muscle strength and endurance, functional capacity, and anxiety were analyzed by making comparisons between the 4th and 8th weeks' evaluations. Results: Differences were found between the 4th and 8th weeks of the patients' dominant hand grip strength and endurance, and between lower extremity endurance and functional capacity. A correlation was found between quadriceps and hip flexor muscle strength and the 6-MWT distance in both evaluations. It was determined that upper extremity muscle strength and hip flexor muscle strength in week 8 are associated with anxiety. Conclusion: It is thought that it would be useful to make comprehensive evaluations that peripheral muscle strength and endurance are associated with functional capacity and anxiety. Improving peripheral muscle strength in the rehabilitation process after CABG surgery may have positive effects on functional capacity and anxiety.
